The Eton Road Torq is a simple device: toss it in your car (where you hopefully never have to use it). In the event you do need it, dig it out from under the seat, crank the dynamo for two minutes and use the 1 watt LED light for 15 minutes. Alternately, you can pop out the tripod legs, flip the flash light head open and use the light as an emergency beacon. $40. [Eton and Brookstone]
